Spastic paraplegia Type 3A is an autosomal-dominant pure or uncomplicated hereditary spastic paraplegia. It is caused by mutations in SPG3A, the only gene associated with this condition. We identified a novel mutation, c.1040T>C (p. M347T), in a family with axonal neuropathy in addition to spastic paraplegia. This expands the spectrum of neurologic… (More)

Hereditary ataxias associated with cerebellar atrophy are a heterogeneous group of disorders. Selection of appropriate clinical and genetic tests for patients with cerebellar atrophy poses a diagnostic challenge. Neuroimaging is a crucial initial investigation in the diagnostic evaluation of ataxia in childhood, and the presence of cerebellar atrophy helps… (More)

Evaluation of imaging studies of the cerebellum in inherited neurodegenerative disorders is aided by attention to neuroimaging patterns based on anatomic determinants, including biometric analysis, hyperintense signal of structures, including the cerebellar cortex, white matter, dentate nuclei, brainstem tracts, and nuclei, the presence of cysts, brain… (More)

AIM
The aim of this study was to identify clinical and radiological predictors of activities of daily living (ADL) outcomes in children with cerebellar atrophy.
METHOD
Over a period of 5 years, we evaluated 44 participants (25 males, 19 females) children with confirmed cerebellar atrophy using magnetic resonance imaging (MRI). The median age at the time… (More)

Angelman syndrome is a neurodevelopmental disorder characterized by global developmental delay, mental retardation, seizures, microcephaly, and severe speech delay. It may be caused by deletion of chromosome region 15q11.2 of the maternally inherited chromosome, mutations in the UBE3A gene, uniparental disomy, or imprinting defects. Most patients with this… (More)

Merosin-deficient congenital muscular dystrophy is an autosomal recessive disease that can manifest differently in different ethnic groups. This often presents as a floppy infant, and normal mental development. The creatine kinase is usually elevated with white matter abnormalities on brain imaging. In this report, we describe an infant with… (More)
